Bash-wrapper-functions

Internal

• Projects Patterns

Overview

A project that offers common bash wrapper functionality in form of a single function file to be sourced in the main wrapper, and a main wrapper template ("application-shell-wrapper-template")

Functionality:

• Basic error/warn/debug functionality.
• Building a classpath based on the JAR content of a repository.
• Getting the Java binary based on a combination of command line options, the content of the JAVA_HOME environment variable, and the "java" binary available in path.
• "Light" version reporting functionality, which relies on the presence of the lib/VERSION file.

Command line argument handling:

• Everything that is enclosed in double-quotes is passed as such to the java runtime as one argument, even if it includes spaces. The current implementation is faulty, multiple spaces are converted to just one space, fix. When fixing, start adding tests.
• Escaped quotes are passed to the java runtime.
